Slava Derbenev

Continued working on JLEIC design and accelerator R&D, particularly, revisited the concept using the electron storage ring as the large ion booster, made some improvement, gave a presentation at the JLEIC R&D meeting
Continued working on unified field theory

Fanglei Lin

Initiated SuperB local chromaticity correction scheme to the electron collider ring.
Working on a couple of electron ring optics to reduce the emittance.
Continued discussion on the possibility of polarized positrons in the JLEIC for a LDRD proposal.
Miscellaneous: attended bi-weekly non-linear beam dynamics meeting, attended JLEIC modeling and JeDi meeting, attended weekly EIC detector user meeting, attended weekly JLEIC R&D meeting, attended CASA group meeting.

Vasily Morozov

Ion polarization: teleconference with Anatoliy's group, spin tracking, IPAC 16 paper
Non-linear dynamics: teleconference with SLAC, ion injection optics, beta squeeze, IPAC preparation
